For the sake of completeness, whenever PHP encounters a reference to a
variable which has not been set it will throw a warning.
The reason most people don't see that behavior is that their version of PHP
uses the default setting of "show all errors but don't mention the
warnings". If they use:
error_reporting(E_ALL);
...they'll probably see a whole bunch of ugly little warnings. Useful for
debugging, annoying as all heck for production code.
